General Description of the Parathyroid Gland

4-5 parathryid glands are embedded in the thyroid gland. Primary hormone is Parathyroid Hormone (PTH) Not dependent on pituitary or hypothalamus.

Physiological effects of the bones of PTH

reduces the effect of new bone formation. Increases the amount of bone degradation which yields calcium and phosphate.

Physiological effects of the kidneys of PTH

causes calcium to be reabsorbed from urine and renter the blood. PTH causes phosphate to be removed from bone into the bloodstream. PTH inhibits the reabosrption of phosphate.

first hormone secreted by the blastocyst, detected in maternal plasma and urine about 3-9 days after conception.

Function of hCG

matins the corpus luteum, stimulates secretion of progesterone and estradiol, stimulates fetal adreanal glads, in male fetuses, stimulates the early secretion of testosterone which is critical to masculinize the genital tract.
